EMBROIDERINGr-MAGHINE.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed December 23, 1916. Serial No. 138,670.

To all whom itmag concern: Be it known that I, IDA DIEM-BEUTLER, a citizen of the Swiss Confederation, and residing at St. Gallen, Switzerland, have in vented certain new and useful Improvements in Embroidering-Machines, of which the following is a specification.

The present invention has reference to im provements in embroidering machines and relates more specifically to embroidering machines having a plurality of superposed tiers of operating mechanisms, each tier comprising a series of adjacent complete stitching mechanisms or units, as well known in the art; and the particular object of the invention is to provide means whereby certain, preferably alternate, stitching units in each tier maybe vertically and horizontally displaced relative to the remaining stitching units in the same tier, with the result that the thus spaced-apart two sets of stitching units then operate with all the needles simultaneously to produce on the ground fabric two or more parallelly superimposed rows of the pattern.

In order to make my invention more readily understood, I will now describe it with reference to the accompanying drawing, in which Figure 1 represents an example of work which can be done on the improved machine; Fig. 2 shows a fragmental front View of a shuttle embroidering machine embodying my invention, set for ordinary onerow work; Fig. 3 shows a side elevation thereof, partly in section; Fig. 4 represents a side elevation, partly in section, and Fig. 5 a fragmental front elevation of the machine, as set for two-row operation; Fig. 6 shows a detail part. Fig. 7 shows a diagrammatical side elevation of a multi-tiered embroidering machine embodying my invention, set for ordinary one-leveloperation, and Fig. 8 represents a similar View, set for two-level operation.

The design. or pattern shown in Fig. 1, which consists, by way of example, of a series of triangles in parallelly superposed rows, the triangle rows being arranged in staggered relationto one another, 18 in the so-called double repeat of the needles, that is to say the needles are spaced apart and operate or repeat at doubly the distance of a single repeat? machine. If the inch is taken as standard, we have one inch repeats, two inch repeats, and so on. In our example we have a two inch repeat with the figures of the superposed rows overlapping halfways relative to the repeat. The horiz ontal distance between the division lines a-b corresponds to the distance between the individual complete units of stitching mechanisms of a machine having a single (one inch) repeat, while the horizontal distance between the lines aa, or bb, corresponds to the distance between the operating units of a two inch repeat machine. Each triangle extends over two one inch repeats and for this reason can only be made in special two inch machines, or in one inch machines only in case each second needle, for instance those corresponding to the lines 6, has previously been removed or otherwise made inactive. But even then only one work row can be made at a time, either row I or row II, but not both rows simultaneously, as can be done by the aid of my invention.

For the purposes of my invention I arrange the stitching units on relatively displaceable supporting members; that is to say, I arrange certain of the units on the usual rigid supporting member, and certain others on a movable member, which latter when displaced upwardly and, if required, also laterally relative to the rigid support, will cause its units to operate on a difierent level from the not displaced units, so that the same design may be worked out simurtaneously along the two parallelly spacedapart rows I and II. Accordingto the example chosen for purposes of illustration, the displaceable stitching units, corresponding to lines I), operate along row I, and the rigid units, corresponding to lines a, work along row II. Obviously, then, it is possible to operate on double the number of needles, than was heretofore possible, and in working up a design with a two inch repeat on a one inch machine, all of the needles are actively engaged and not only the half of them as formerly.

Referring to the drawing, there is provided alongside of theusual needle bar 1 a second needle bar 2, and screw bolts 5, operating through slots 3 and a in the needle bars, serve to clamp the latter together. On these needle bars are alternately arranged the needle carriers or socket arms 6, 7, in such manner that all socket arms 6 extend from the bar 1, and all socket arms 7 from the bar 2. The needles 8 are secured in their sockets in well known manner. Near the ends of the bar 2 are provided cut-outs 9 in which engage the eccentrics 10, whose pivots 11 are operatively secured in the bar 1. These eccentrics (shown in side elevation in Fig. 6) are provided with square sockets 12 for receiving a removable socket wrench, not shown, for actuating purposes.

In like manner there are provided two shuttle guide bars 13 and 14, which are relatively displaceable and can be clamped together by screw bolts 17 passing through slots 15 and 16 in the respective guide bars. The shuttle races 18 and 19 are alternately so located on these guide bars, that the races 18 are on the bar 13, and the races 19 on bar 14; and we have here, likewise, near the extremities of the shuttle track bars eccentrics 21, such as described above, which are pivotally secured to the bar 13 and operate in cut-outs 20 provided in the bar 1 1.

The shuttle driver bars 22, 23, supporting the shuttle drivers 24 and the slides 25, are similarly relatively displaceable. As all these parts as such, as also the impelhng means, in their construction, arrangement and cooperation are well known in the art,

special description and illustration thereof is deemed unnecessary here.

For ordinary work the machine elements would be in the position shown in Figs. 2

and 8, the machine then operating on all needles along one row like any ordinary embroidering machine. If it is desired to work simultaneously on two superimposed parallel rows, the screw bolts 5 are eased and the eccentrics 10 are actuated until the needle arms 7 are suliiciently raised above the needle arms 6. In addition to this vertical displacement, the needle arms 7 can, if necessary, be also shifted longitudinally to the extent of the slots 3 and 9 respectively. The screw bolts 5 are then tightened again, which relatively locks the two needle bars. Next, the screw bolts 17 are loosened and the shuttle tracks 19 are raised and, if necessary, laterally displaced, care being taken, of course, that all of the respective cooperating elements are in correct relative position. On tightening the screw bolts 17, the shuttle track bars 13 and 1 1 are locked on one another. Finally, the shuttle driver bars are similarly adjusted and locked.

The two interspaced embroidering sets in each tier, which are driven in well known manner by a common impelling mechanism,

now operate simultaneously, only on different levels, the undisturbed set operating on the pattern row I, and the raised set on row II.

It is obvious that also more than two rows may be worked upon in case arrangements are provided whereby the stitching units can be relatively displaced to operate on three or more levels; and designs may be executed, by using all needles simultaneously, which extend across more than two rapports or sections of the machine; and, lastly, designs may be worked, the figures of which can be arranged vertically above one another in the several rows, and not relatively staggered, as shown.

For using the machine again as ordinary one-row embroidering machine, the cooperating unit parts are adjusted back to the position shown in Figs. 2 and 3.

What I claim is y 1. In an embroidering machine including tiers of normally alined complete stitching units, means for displacing certain of these complete units relative to certain others in the same tier without altering their operative distance from the fabric operated on, for the purpose of obtaining in each tier parallelly superposed rows of simultaneously operable complete stitching units.

3. In an embroidering machine, a sup porting structure, tiers of normally alined stitching units supported by said structure, each such unit comprising the needle and the shuttle and their respective operative mech anisms, means for vertically displacing certain of these complete units relative to certain others in the same tier, for the purpose of obtaining in each tier parallelly superposed rows of simultaneously operable complete stitching units.

4. In an embroidering machine, a supporting structure, tiers of normally alined complete stitching units supported by said structures, means for vertically displacing each second complete unit relative to the re spective other complete units in the same tier, for the purpose of obtaining in each tier parallelly superposed rows of relatively staggered complete stitching units, all adapted to operate simultaneously and in un1son.
